International classification of diseases/disorders diagnosis and International Classification of Functioning, Disability and Health activity/participation limitation among psychiatric patients: a cross-sectional and exploratory study.

Abstract

To explore the relationships between international classification of diseases/disorders (ICD)-10 diagnoses and International Classification of Functioning, Disability and Health (ICF) disability dimensions - activity and participation restriction among mental health service users. Three hundred sixty patients from different health services diagnosed with diverse mental disorders (ICD-10) participated in the study. Functioning restrictions were evaluated by use of the Mini-ICF-APP. Selected sociodemographic and clinical variables were also analysed. The Mini-ICF-APP scores correlated positively with the clinical impression of disease severity and negatively with general functioning. As independent factors determining the Mini-ICF-APP score, regression analysis suggests diagnosis and severity of disorder but also contextual factors such as general functioning and active occupation. Percentage and percentile distributions of activity and participation restrictions in diagnostic sections and categories revealed noticeable variability regardless of diagnosis-related differences. The diagnosis determines them neither in an ambiguous nor an absolute manner. There is a need to further explore the covariability between clinical diagnosis and ICF activity and participation restriction, particularly in regard the rationalization of social welfare benefits.
